chromophore has been incorporated into the turn region of a 42 amino acid peptide, linking two helical peptide sections. Spatial proximity between these sections, as well as aggregation into dimers, is required to facilitate the catalytic function of this artificialhydrolase. Photomodulation of the hydrolase activity results in an increase of the activity of 42 % upon switching from the trans to the

standard spectroscopic techniques (nuclearOverhausereffects, amide temperature coefficients, circulardichroism spectroscopy), the applicability of self-diffusion measurements (longitudinal eddy current delay pulsed-field gradient spin echo (LED-PGSE) NMR technique) in conformational studies of oligopeptides is demonstrated. The title compound shows photoisomerization of the stilbene chromophore, resulting
